CollectionOf

Provides an Enumerable which acts as a collection of a certain type of object (and its subclasses, unless allow_subclasses is set to false on initialization).

Usage

WidgetCollection = Collection[Widget]
# OR WidgetCollection = Collection.of(Widget)
# OR WidgetCollection = Collection.new(Widget)

wc = WidgetCollection.new
wc << Widget.new # all good!
wc << Wadget.new # => ArgumentError, "can only add Widget objects"

When a Collection is cloned, any items contained within the collection are cloned as well.

wc << Widget.new(:one)
wc << Widget.new(:two)
wc[:one] == wc.clone[:one] # => false

Installation

Add this line to your application's Gemfile:

gem 'collection_of'

And then execute:

$ bundle

Or install it yourself as:

$ gem install collection_of
